VoIP socket for ios app?

Question

iOS

There is an application that works in the background, I created a socket through a lib , I clearly let it know that it should work in the background, Everything should be fine, but after 15 minutes of work in the background, the socket is killed :(

Who has come across what can be done to make the socket did not close and continued to work.

Answer 1

- (void)backgroundHandler { NSLog(@"### -->VOIP backgrounding callback"); UIApplication* app = [UIApplication sharedApplication]; bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; }]; } - (void)applicationDidEnterBackground:(UIApplication *)application { BOOL backgroundAccepted = [[UIApplication sharedApplication] setKeepAliveTimeout:600 handler:^{ [self backgroundHandler]; }]; if (backgroundAccepted) { NSLog(@"VOIP backgrounding accepted"); } UIApplication* app = [UIApplication sharedApplication]; bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ [app endBackgroundTask:bgTask]; bgTask = UIBackgroundTaskInvalid; }]; }
I found a solution to the problem, added such code to the appDelegate and everything is working fine now in the background. There are few places where you can find a description of this.
